I don't actually have an issue with my battery as far as lifespan is concerned. With a mix of phone calls, web browsing, mail and some playing on Weather/Stocks/YouTube I get about 2 days before I need to charge to be confident I can make it through the next day without dying.

My iPhone does, as several people seem to experience, not charge to 100% when plugged in. It gets to what looks like 95-98% and stays there. However, I have found a solution that seems to all get me the extra couple percent and wanted to share with everyone.

I plug my iPhone up when I go to bed - roughly 12:00am and let it charge until 7:00am when I wake up. When I get up I leave it plugged up, but I turn it off (holding the Sleep/Wake button until the red slider appears), wait 20 seconds and turn it back on - again, never unplugging the phone.

I then go and do all the morning crap I do to get ready for work. At around 7:45/8:00am I go and wake my iPhone and I now have a 100% charged battery as indicated by the bar being full green and the battery glowing and reset usage settings.

I've been doing this for about 2 weeks now - equal to about 6 full charges and each time I reached 100%. Before this I was hitting roughly 95-98% on each charge.

It works for me, so maybe people that aren't getting reset usage settings and have never seen the green glowing battery might find this works for them as well.

What I have done is just wake the phone up from sleep, which clears the battery graphic and then let it go back to sleep, once it goes back to sleep it has been showing 100% and glowing. I also keep it plugged in while doing this. I'm not sure if it is just a matter of the screen not updating those last few percentages.

I'm sorry for resurrecting an old thread, but is this still a problem for new iPhones? I just bought mine less than 2 weeks ago, and I just noticed (I'm in college right now) that it keeps stopping about 1 cm (90-95%?) from "full". I keep it charged via USB to my MBP before I go so sleep every night (12:00 AM), and when I get up (8:00 AM), it's charges up to there. Because of a lack of outlets in my room, I don't use the wall power adapter.

I'm going to try the above strategy today, actually right now. I just want to make sure that even on the newer iPhone batches, I'm not the only one?!?

I just bought an 8gb last week and I have this same problem still... I've tried restoring and draining the battery but nothing worked! Looks like I'll head back to the Apple store tomorrow!

Add me to the list. Got a refurb 8gb a few days ago and have this same problem. Just wont fill that last millimeter or so, but the lightning bolt changes to a plug, indicating its fully charged. Plus my usage stats dont work because it never gets fully charged.

Just curious, I bought it online from Apple. I have an Apple store within driving distance. Is this something they can diagnose there?? I mean, how exactly are they going to be able to tell my battery wont fully charge?
